MonsterVision is an American variety series that aired on TNT from early 1991 to September 2000. ( There is no clear air date for the first MonsterVision but the oldest known video footage of the marathon is from 1991.) The series was hosted by Joe Bob Briggs from 1995 to 2000, and featured mainly classic horror and schlock films from the 70's, 80's, and 90's.
Before the arrival of Joe Bob Briggs as a permanent host, a claymation style moon character narrated the bumper segments and served as the de facto host. Later, Penn and Teller guest-hosted MonsterVision marathons featuring mainly old B-Movies from the 50's and 60's. Late in its run, the show changed formats, discarded "Last Call," and became Joe Bob's Hollywood Saturday Night and Monstervision.
